Letters Patent No. 83,380, dated Octobeo` 27, 18,68.

IIVIPROVEIVIENT IN CHEK-'V'ALVES FOR STEAM AND OT'HER ENG-INERY.

The Schedule referred to in these Lettera Patent and making part of the same.

To whom fit ma/y concern.-

Beit known that I, J OEI. HAYDEN, Jr., of Haydenville, Hampshire county, Commonwealth of Massachusetts, have invented a new and useful Improved Check- Valve for Steam and other Fluids and Liquids; and I do hereby declare that the following is a full and clear description thereof, reference being had to the aecompanying drawings, and to the letters of reference marked thereon.

The drawing is a sectional view through my valve, showing its interior arrangement.

This invention consists 1n an improved combination of parts, with reference to a valve, by which a fluid Betweenthis chamber and the outlet D is the parti` tion A, with the valve-seat B, into which iits the valve J, conieally shaped, and attached to a rod, G, which has also a cup, F, securely attached to it, and closing in between it and the sides of the chamber F.

The valve is opened by means of direct pressure against the rod G, either to' push it up from the bottom, or pull it upiom the top, as may be most oonvenent.A

The operation of this valve is as Ifollows: When' the valve is opened forcibly, by outside pressine against the rod G, the uid passes through the valve-opening, and has a free ilow from the inlet to the outlet, until the force is withdrawnom-the rod G, and then the pressure'of the iuid against the cup Fforces it down, and with it the valve and rod G, thus closing the opening, and shutting oiil further supply.

Having described my invention,

What I claim as new, and desire to secure by Letters Patent, is Theoombinaton of the valve J, cup F, connectingrod Gr, outlet D, and inlet C, with the partition A and valve-seat B between them, whereby the fluid or liquid is enabled to close the valve byits pressure against the cup, when the valve is relieved from outside force, substantially as herein described and shown.
